GLOSSARY
Ledger
System of record that tracks debits and credits for balances, payouts, and fees.
A ledger records debits and credits for accounts such as customer balances, disbursements, refunds, and fees. Ledgers provide auditability and prevent double-spend by enforcing ordered postings and invariants.
Payment platforms often ledger holds, settlements, and reserves, then export to accounting tools. Accurate ledgers simplify tax (e.g., VAT) and reconciliation with processors and banks.
